Ever notice that all government vehicles on TV or undercover vehicles are either black SUV's or Sedan's with black tinted windows?
If you ever look in your rear view mirror and see one of these PLAIN black vehicles following you and you can't see inside because the windows are so dark, well you are probably being followed. Probably by the FBI or the local federally or something.
Maybe you should choose this moment to think back on what you did recently for them to be following you. Maybe a website you visited, a phone number you misdialed on accident, or maybe it was one of those books in the library you checked recently. Maybe that book was on the red flag list.
I'm just sayin'.
I've already called mine! :)
